JFFS2 on Samsung NAND

[srinath.satyanarayana at wipro.com]

Hi ,

I am using linux-2.6.12 and Redboot on my board.  I have Samsung 32Mb,
16Kb erase block flash on my board
I am not able to mount the  jffs2 partition of NAND.
The procedure followed

mkfs.jffs2 -d jffs2  -n -o fs.jffs2 -e 0x4000 --pad=0x400000
flasheraseall -j /dev/mtd/7
nandwrite  /dev/mtd/7 fs.jffs2
mount -t jffs2 /dev/mtdblock/7 /mnt


Node at 0x00003eec with length 0x00000615 would run over the end of the
erase block Perhaps the file system was  reated with the wrong erase
size?

Further such events for this erase block will not be printed

Is steps followed  are corrent? Any suggestion is appreciated.

Thanks
